I know this is an old topic, but I normally weigh myself almost every day, but I usually pick a day out of the week to use a a baseline every week based on my habits and schedule. For me that’s usually Wednesday, which is the first morning after my first workout of the week. I’m trying ensure I don’t have excess water weight on board because of my Monday day off the bike and Wednesday seems to be the most consistent baseline for me. I do it first thing in the morning after using the restroom.
I mostly look at trends for weight and if my 7 day average weight changes, I’ll update my weight on various apps.
This…honestly, until this thread, it never occurred to me to even look at it. It doesn’t affect the trianing programs so I don’t really care. I know it within ~2kg / 5 lbs or my weight at any point, which is close enough…
Auto sync weight to the platforms I use and then a ignore it.
Like a few others have mentioned, I use my bodyweight as an indicator of my calorie consumption - weight down = need to eat more, weight up = eating a little too much, weight stable = just right.
I weigh myself each morning, post-bathroom and pre-liquid / food, and then take the rolling average, ignoring any day to day variation.
I use the monthly average and update my weight based on that on the first of each month
Yeah, I didn’t know that was an option and I may look into it…but then again, I’m not too terribly concerned about it for TR. If I was racing on Zwift regularly, then maybe…
We bought a Withings scale a couple months ago after the Fitbit died (10 years, RIP). After a couple weeks getting double and triple weight in TrainingPeaks, I disabled a few things in Apple Health and now TP gets 1 weigh-in a day, but Garmin Connect is hit or miss. I can’t be bothered to figure out how to fix that, even though it impacts the current 2.99 and 3.00 W/kg teeter-totter on my bike computer 
Using best bike split opened my eyes to how little weight changes things.
I weight every morning and record it on my fitness Pal (6ft 2, 168lb want to get down to 162-164lb region).
But in terms of TR, only change weight when I change FTP (e.g. ramp test or similar).
Does TR keep track weight yet? If not then forget syncing and your system is a great one!
Thanks! I have a Withings Body+ and Garmin Index S2 side-by-side. SmartScaleSync has caught up and is pushing all my Withings data to Garmin Connect and TrainerRoad. From there it finds LoseIt (my app for tracking calories/macros…). I think I"m returning the S2 scale tomorrow. I"m not seeing any major difference in readings that I care about. I suspect the ability to tweak your activity level vs. just choose athlete or non-athlete mode may be the way to dial it in, but without a DexScan to compare it to, I do not really care.
fwiw I’ve have compared the scales to a dexa (not readily available here, but I took part in a wider genomics study), and it was accurate once I switched to “Athlete Mode”. I was actually quite surprised how good it was, given the reputation of such scales (and the €25 option I took).
Excellent. I assume you are referring to the Withings Body+. Out of curiosity, were you extremely lean at the time? I am far from “lean” and assumed not using athlete mode would be most accurate. I was also curious if two titanium hips made a big difference, not that I am overly concerned with the final number just a consistent and repeatable number for trending data.
No, I’ve “Renpho” scale. I wasn’t heavy but (i’d still) considered myself skinny fat. I do very little off bike work, so hadn’t selected Athlete Mode. The survey was near my work, so I had the scales in the car, and checked within half an hour of the dexa.
No idea on Ti hips, but the impedience scales generally have a bad reputation, which is part of the reason I didn’t pay big. I was just thinking consistency, rather than accuracy.
Makes total sense. I understand the limitations of impedance and weighing yourself daily. Consistency and trending are the goal for me as well along with the convenience of the numbers just populating into GarminConnect. Now that I have Patrick’s sync service working, I’m going to just keep the Withings unless I find some great advantage that justifies the significant cost difference.
Thanks for your input.
